There are no specific rules stating that players must open a bazaar at a certain location. If a player is blocking a passage, it is possible to pass through them by walking in the desired direction for a few seconds. As such, this is not explicitly considered gridlocking. However, players should take into consideration that others may want to pass through a given area, and ensure that paths are not being blocked. GMs may get involved if players are blocking others and ignoring the requests of others to move.
